well this may not help you.. but found this on another site...
Most likely "reasons":

1. The provisioning server does not recognize the ESN/MDN combination of the phone (improperly programmed phone)

2. The subscription is not provisioned for IP services (due to improper setup or provisioning times/delays)

3. Less than ideal Sprint signal reception (provisioning does not work while roaming)

Troubleshooting steps to try: (these are assuming the subscription is properly provisioned for IP services, and the phone is programmed properly)

1. Battery removal for one or more minutes (Do not power off phone before removing battery)

2. Make sure the phone has two or more bars of signal

3. Attempt a phone call. If you cannot complete a call, the phone will not provision data services

4. Update Vision Profile (can be found at 'Menu/Settings/(Power) Vision/Update Profile')

5. Total Device Reset (erases everything, sets phone to factory defaults, requires MSL, re-programming of MDN/MSID is necessary afterwards). This step is usually done in a store or with the assistance of technical support.

An error 1012 may also have underlying issues such as other error codes that may require additional assistance from technical support.
